Part Number: BQSTUDIO Other Parts Discussed in Thread: BQ27Z561 , GAUGEPARCAL Tool/software: I am using BQ27z561EVM to try to get the GPC log to get the chemID for my board. Is there any instruction how to use the EVM with bqStudio and step by step to…
Part Number: BQ78350 Other Parts Discussed in Thread: GAUGEPARCAL ,
Hello
For an 8S family of battery packs I have just provided data to GAUGEPARCAL and obtained a set of parameters as follow:
EMF 3802 EDVC0 519 EDVC1 0 EDVR1 1 EDVR0 439 EDVT0 1…
GPCRB is for temperature optimization, which is an optional step.
If this make/model isn't in the database then you can substitute with a compatible model. You can find compatible ChemIDs using a web app: https://www.ti.com/tool/GAUGEPARCAL, www.ti…
The SOC jump after OCV measurement indicates that the chemistry isn't compatible with the built-in ChemID (0128 for the G1-A and 0312 for the G1-B) because a significant adjustment from OCV means that DOD changed unexpectedly.
This is less about a low…
Part Number: BQ27220 Other Parts Discussed in Thread: BQSTUDIO , GAUGEPARCAL , AM62A7 Hello TI, I am successfully able to updated the Design Capacity of bq27220 from 3000mAh to 9000mAh but the FCC "Charge Full" parameter is still 3000mAh.
One of your…
This can happen for many reasons. The gauge uses Terminate Voltage as the stop condition for its capacity prediction. If it predicts that the cell voltage drops below 3000mV before the real cell voltage drops to 3000mV then it is possible for the gauge…
Hello Vinay, The only thing that I can advise on this matter is to follow the application note, to recheck the critical parameters you set, and make sure that you follow the sets for the cell chemistry you are using.

#1: This is done by sending the IT_ENABLE command. This is a sub-command and will only work if the gauge is unsealed. Write 0x21 to register 0x00 and 0x00 to register 0x01 (=subcommand 0x0021 in little endian) to execute this command while the gauge is…
